Mine's in my ex-husband's house (yes, I was still there when I built it). It's in the basement and is about 10x10ish. I can still use it, so I'm not building another one 'til I have enough room and darkness (my apt has too many windows and not enough space).

My current darkroom is in my basement, purpose-built. It's kind of small, about 7'x8', but it gets the job done admirably. I can do enlarging up to 16x20 from 35mm-4x5 negs, and alt process to 11x14". All my previous darkrooms have been various bathrooms in the apartments I've had. I had an IKEA cart that I used to put the enlarger on top (and was the perfect size for the baseboard), and the Nova vertical processor underneath, so the whole kit could be wheeled in and out in a few minutes. When not in use, the remaining kit could be wheeled into the walk-in closet in the master bedroom for storage.

My current 'darkroom' is nothing more than a tiny bathroom. My enlarger sits on a small rolling cart which I wheel into the bathroom. I sit on the toilet and can print pretty comfortably.. My trays sit in the tub, easy to clean up afterwards.

Hardest part is setting up everything. I was spoiled, having a dedicated darkroom with a wet room and a dry room. Ah well. I miss having a 'real' enlarger. I'm using an Omega C760 (flimsy) but used to use an Omega DII (workhorse)..

Was sharing space in the laundry room for several years which is a pain because everything neds to be covered when not in use and then I have to run a misting humidifier before use to help settle lint and dust.

Since just after Christmas we have been doing a remodeling of the basement and a dedicated room has been in the works. Worst part is the darkroom is the last room to get finished.
